And even once everybody starts using STREAMS, you'll *still* keep it
(although modified for STREAMS), since streams modules run in the
kernel.

However, don't assume that there "isn't any better way to do it without
bringing the system to its knees" before trying one of the other ways;
try snarfing Ken Almquist's "atty", for instance, if you have
BSD-flavored pseudo-ttys.
